TECHNICAL FIELD

[0001] The utility model mainly relates to the field of myopia prevention paper and notebook, specifically a kind of myopia prevention paper and work book for relieving eye fatigue. BACKGROUND

[0002] With the improvement of living standards and the promotion of education reform, people pay more and more attention to students' vision problem. Among them, myopia prevention paper is favored by people. Myopia prevention paper usually uses yellow, green and beige with low reflectivity as the base color, so as to reduce the intensity of reflected light and relieve visual fatigue.

[0003] The heterochromatic paper for relieving visual fatigue can better relieve visual fatigue and protect vision in the case of sufficient light, but not always in the light environment during the learning process, especially in the classroom, without the light source of desk lamp, the light is not so sufficient, and the brightness of heterochromatic paper may be dark, which needs to consume more eyesight to identify the content, and visual fatigue may be aggravated due to difficult identification. UTILITY MODEL CONTENT

[0004] To solve the problems of the prior art, the utility model provides a kind of myopia prevention paper and work book for relieving eye fatigue, which can improve the light reflection performance of paper by the interlaced setting of mesh lines, and white and heterochromatic color are set alternately, which can relieve visual fatigue and ensure clear feedback of handwriting.

[0005] The utility model discloses the following technical scheme to realize the above-mentioned purpose:

[0006] A kind of myopia prevention paper for relieving eye fatigue, including paper sheet, the paper sheet is semi-transparent paper, the light transmittance of paper sheet is 38%-42%, the paper sheet top surface is equidistantly set mesh line, so that the D65 brightness of paper sheet is 55%-65%, the mesh line is light yellow or light green arc line, the distance between adjacent mesh lines is 0.1-0.3mm, black grid line or horizontal line for guiding writing is set on the paper sheet;The paper sheet top surface is provided with a matte layer.

[0007] Preferably, the mesh line is a circular arc line with consistent diameter.

[0008] Preferably, the mesh line is a dotted line.

[0009] Preferably, the paper sheet edge has a blank frame, the paper sheet inside is a writing position, the blank frame is 0.5-1cm, and the mesh line, grid line or horizontal line is located in the writing position.

[0010] Preferably, the top of the paper pages are bound together to form an exercise book. The exercise book has a back cover, which is a hard cover. At least one side of the back cover is provided with a pad, which is bright yellow or bright green.

[0011] Preferably, a soft connecting piece is provided between the pad and the back cover.

[0012] Preferably, the soft connecting piece has several rows of pressing holes arranged vertically, and the pressing holes in the same row are connected to form a bend line.

[0013] Preferably, there are two pads, which are symmetrically arranged on both sides of the back cover, and the two pads have different color brightness levels, one higher and one lower.

[0014] Preferably, the contact surface between the pad and the back of the paper is a frosted surface.

[0015] Compared with the existing technology, the beneficial effects of this utility model are:

[0016] This invention draws inspiration from the grid effect in art. By dividing the paper sheet with evenly spaced grid lines, it can significantly reduce the whiteness of the paper and the intensity of reflected light while ensuring the clear recognition of handwriting. This does not affect the recognition of handwriting, reduces the visual strain on the eyes when reading text, and thus effectively reduces eye fatigue.

[0017] This invention utilizes the semi-transparent nature of the paper, combined with a backing plate, to allow the color of the backing plate to shine through the paper, giving the paper a lighter hue. This allows the reflectivity of the paper to be adjusted according to the light intensity, enabling a more suitable combination under different lighting conditions, reducing eye fatigue and slowing down vision decline.

[0026] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0027] like Figures 1-7 As shown, the present invention discloses an anti-myopia paper for relieving eye fatigue, comprising a paper sheet 1, which is a semi-transparent paper with a light transmittance of 38%-42%. The semi-transparent nature of the paper sheet 1 allows it to be used with a solid-color backing plate 4. By using backing plates 4 with different color shades and brightness levels under different light intensities, different light reflection intensities can be achieved, thus ensuring the most suitable light reflection intensity under various lighting conditions and better relieving eye fatigue.

[0028] The top surface of the paper sheet 1 is uniformly covered with a grid pattern, resulting in a D65 brightness range of 55%-65%. The grid pattern is a light yellow or light green arc, with a spacing of 0.1-0.3 mm between adjacent grid patterns. The light yellow grid pattern reflects wavelengths of 570-590 nm, while the light green grid pattern reflects wavelengths of 500-520 nm. This grid pattern effectively reduces the whiteness of the paper, thereby reducing the intensity of reflected light without affecting the recognition of written text. This reduces eye strain during reading and helps prevent myopia.

[0029] Specifically, the halftone lines are uniformly shaped arcs. This array of arcs ensures color complementation to page 1 without interfering with the writing guide lines. Furthermore, the small spacing between the halftone lines and the absence of a center point between them prevents dizziness caused by prolonged direct viewing. More specifically, the halftone lines are dashed. This dotted line arrangement further utilizes the grid effect, making the text clearer, easier to read, and reducing eye strain.

[0030] Black grid lines or horizontal lines are set on the paper to guide writing. The grid lines and horizontal lines guide writing and are not parallel to the grid lines to avoid the grid lines interfering with the writing direction.

[0031] Furthermore, a matte layer 2 is provided on the top surface of the paper 1. The matte layer 2 can reduce the brightness of the paper, thereby reducing the reflective intensity of the paper and alleviating eye fatigue caused by prolonged desk study. The matte layer 2 can be roughened using a brushing process.

[0032] More specifically, the paper 1 has a blank border 11 along its edge, and the inside of the paper 1 is a writing area 12. The blank border 11 is 0.5-1cm long, and the halftone lines, grid lines, or horizontal lines are all located within the writing area 12. The blank border 11 makes the paper 1 more aesthetically pleasing, and the light reflected from the blank border 1 can balance the brightness of the writing area 12, further reducing eye fatigue and having a certain preventive function against myopia.

[0033] This invention provides a type of paper that can relieve eye strain and prevent myopia. The paper pages are bound together to form an exercise book, meeting daily study needs. The top of each page 1 is glued, and the outer sides are protected by a front cover and a back cover 3. The back cover 3 is a rigid cover, and at least one side of the back cover 3 has a pad 4, which is bright yellow or bright green. The color of the pad 4 matches the color of the grid lines. The pad 4 supports the writing page 1, ensuring writing stability. A flexible connecting piece 5, made of soft plastic, is provided between the pad 4 and the back cover 3. The end of the flexible connecting piece 5 is glued to the edge of the pad 4.

[0034] The area of ​​the pad 4 is slightly smaller than the area of ​​the paper 1 but larger than the area of ​​the writing position 12. The pad 4 can cover the area of ​​the writing position 12, thus serving as a backing for writing.

[0035] Specifically, there are two pads 4, which are symmetrically arranged on both sides of the back cover 3. The two pads 4 have different brightness levels, so that when the semi-transparent paper 1 is covered and written on, the color of the paper 1 can be adjusted. This allows for adjustment of the intensity of reflected light from the paper 1 under different lighting conditions, enabling the paper to be matched with different materials under different lighting conditions to adjust the intensity of reflected light and maintain a relatively comfortable reflected light condition for writing, thus relieving eye strain.

[0036] Specifically, the flexible connecting piece 5 has several rows of pressing holes 51 arranged vertically along its upper edge. The pressing holes 51 in the same row are connected to form a bend line. This allows the flexible connecting piece 5 to be stacked on the back cover 3 for easy storage when not in use, and it is easier to use with the paper 1 when in use, without slipping due to the elasticity of the flexible connecting piece 5 itself.

[0037] The contact surface between the pad 4 and the back of the paper 1 is a frosted surface. The frosted surface can increase the friction between the pad 4 and the paper 1, thereby preventing the paper from slipping during writing and ensuring a good writing effect.
